example, this information might be that a logical path has been broken because of a

d. Select (enable) or clear (disable) the Suppress RSCN on Zone Set Activations check box.

When the parameter is enabled, attached devices do not receive notification following any

change to the fabric's active zone set.

When the parameter is disabled, attached devices (registered through the fabric format

e. Select (enable) or clear (disable) the Limited Fabric RSCN check box.

When enabled, RSCNs are not transmitted after a product initial program load (IPL).

f. Select (enable) or clear (disable) the Zone Flexpars: Isolate Fabric RSCNs on zone activation

changes check box.

When enabled, zone FlexPars isolate and prevent fabric-format RSCNs from propagating to

devices in zones that are not impacted.

g. Enter a value from 1 through 31 (default is 1) in the Preferred Domain ID box.

The domain ID uniquely identifies each switch in a fabric.

NOTE: All fabric-attached switches must have a unique domain ID. If the value is not

unique, the E_Port connection to the switch segments and the switch cannot communicate

with the fabric.

h. Select By Port Speed or Ignore Port Speed from the ISL FSPF Cost Configuration drop-down

list.

• By Port Speed—The fastest fabric path is determined by port (ISL) speed. Cost is inversely

proportional to speed.

• Ignore Port Speed—ISL speed is ignored, and the fastest fabric path is determined by the

number of hops. Cost is directly proportional to hop count.
